1 DESCRIPTION AND OPERATION
1.1 Application
The PEF-319 universal automatic electronic phase switch is designed to supply an industrial and domestic
single phase 230/240 V, 50 Hz load from three-phase four-wire mains 3х400+N in order to maintain uninterrupted
power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.
PEF-319 –with additional relay 16 A, PEF-319-30 –with additional relay 30 A.
According to the voltage presence and voltage quality on the phases, the PEF-319 will automatically select the
optimum phase in limits range set by user and switch the single phase load supply to this phase:
-If power is less than 6,6 kW (30 A), the load is energized directly from the PEF-319;
- If power is more than 6,6 kW (30 A), the PEF-319 controls the magnetic starters (MS) single phase coils of the
corresponding power (MS are not included in supply complete package).
The maximum and minimum voltage limits are set by user.

NOVATEK-ELECTRO PEF-319
PEF-319 meets the requirements of: EN 60947-1; EN 60947-6-2; EN 55011; EN 61000-4-2.
Harmful substances in concentration more than allowed are absent.
4 DESCRIPTION AND OPERATION
The electronic phase switch PEF-319 is a microprocessor-based digital device.
User should make setting of trip threshold limits of PEF-319 - the minimal and maximal voltage values at which
PEF-319 trips and switches off the load (or switches over to a reserve phase).
Phase L1 is the priority one. It means that at normal parameters of voltage on all phases connected to PEF-319 (L1,
L2, L3), the load will always be energized from phase L1. If on L1 the value is out of limits set by user, PEF-319 switches
the load to the nearest by priority phase in not more than 0.2 seconds if the its voltage corresponds to the normal level. If
the voltage on the reserve phases does not correspond to the trip set limits the load switches off.
Switching to the phases having the unallowable parameters will not be performed.
After the load had been switched to the reserve phase and the voltage parameters had been restored on the
priority phase, the load will be switched to the priority phase in return time Тr(from 5 to 200 sec) set by user.
During the phase switching there can be a flickering of the red LED indicator ALARM and there will be a short
time indication of alarm code on the display (for example, code “”means that the switching was performed from
the phase L3).
If during count down of Тrthe voltage on priority phase goes out of threshold limits, the timer of Тr
will be reset.
If Тris in the position “∞”, the return to the priority phase will be performed only when voltage on the reserve
phase goes out of the threshold limits.
In case when the voltage supplied on load goes lower than the minimal threshold limit the load switching over or
switching off should be performed with a time delay of 12 seconds. When the voltage goes higher than the maximal
threshold limit or goes 30 V lower than the minimal threshold limit, the load switching over or switching off will be
performed with time delay of 0.2 seconds.
During the load switching off the PEF-319 continues to perform the voltage control on all phases.
When the voltage normalizes within the limit range on one of the phases the PEF-319 will switch the load to this
phase within the time period of Тon.
The additional relay will switch on if the load is connected to any phase.
The additional relay terminals are insolated and designed for enhancement of device functional possibilities.
PEF-319 is designed with an internal blocking system against sealing of relay output inbuilt contacts and with
control of state of magnetic starters power contacts in external circuit (the terminal 1is used for sealing control,
figure 3). If at least one contact is switched on («sealed»), PEF-319 will be blocked, the phase switching over is not
performed, the red LED indicator ALARM is flickering and the green LED indicator shows the phase on which the
sealing took place, and the digital display will for a short time show the code of alarm and number of relay (MS) of а
sealed phase (for example, code “” means a sealed contact on phase L2).
Unblocking of PEF-319 should be made by its de-energizing.
NOTE –There will be no switching over in case of energy presence on terminal 1.
5 INTENDED USE
5.1 Preparation for operation
5.1.1 Preparation for connection:
–Unpack and check the product for damage after transportation; in case of such damages detection, contact
the supplier or manufacturer;
–Check for components (it.2), in case of detection of incomplete product, contact the supplier or manufacturer;
–Carefully study the Operating Manual (pay special attention to the connection diagram to power the
product);
–If you have any questions regarding the installation of the product, please contact the manufacturer by
telephone number indicated at the end of this Operating Manual.
5.1.2 Connection
ATTENTION! ALL CONNECTIONS MUST BE PERFORMED WHEN THE PRODUCT IS DE-ENERGIZED.
Error when performing the installation works may damage the product and connected devices.
To ensure the reliability of electrical connections you should use flexible (stranded) wires with insulation for
voltage of not less than 450V, the ends of which it is necessary to be striped of insulation for 5±0.5 mm and
tightened with bootlaces. Recommended cable cross section for connection is 2.0 mm2.
Wires fastening should exclude mechanical damage, twisting and insulation abrasion of wires.
When reducing the tightening torque, the junction point is heated, terminal block may be melted and wire cane
burn. If you increase the tightening torque, it is possible to have thread failure of terminal block screws or the
compression of the connected wires.
5.1.3 Make connection of PEF-319 to the three-phase line according to the figure 2 (at load value less than 30 A) or
according to the figure 3 (at load value more than 30 A with use of magnetic starters).

PEF-319 NOVATEK-ELECTRO
The limit values should be set after connecting the device to the mains with the load being disconnected:
Umin –the minimal voltage level of relay switching on;
Umax –the maximal voltage level of relay switching on;
Тon –time of automatic reset of load after restoring the voltage parameters on one of the phases, and time of
load primary switching on after energizing of the device;
Тr- time of return to the priority phase.
For the refrigerators, air conditioning devices and other compressor equipment, Тon is recommended to be set
in range of 180 –600 seconds, for other devices –according to their manuals and operating instructions.
After the setting of threshold limit values the device is ready for operation with load.
It is allowed to change the levels of Umin, Umax, Тon, Тrduring the device operation with observing the
safety rules.

QF1, QF2 –Automatic circuit breakers (the breaker nominal is selected according to the power of the connected
loading).

5.2 Intended use
After connection to power supply and parameters setting the PEF-319 is ready for operation.
Green light LED indicators L1, L2, L3 on the front panel show the phase to which the load is connected.
With load being connected the digital display shows the voltage of the phase which is connected to the load.
With load being disconnected the digital display shows the voltage of the phase which has the value nearest to
the set threshold voltage limits. This phase is indicated by flickering of corresponding LED indicator.
If the load is disconnected from all three phases, the red LED indicator ALARM will light on.
In case when several PEF-319 devices are used in the line, it is recommended to select different phases as a
“priority one” for different groups of consumers to avoid the phase overloading.
In case in mains several PEF-319 is used, for prevention of an overload on phases it is recommended as
priority to choose different phases for different groups of consumers.
